#### Detailed Explanation:
An **amide functional group** is characterized by a carbonyl group (C=O) attached to a nitrogen atom (N). In the list provided, you can identify which compounds have this structural feature to determine those that contain amide functional groups.
- **Compound I** shows a carbonyl group (C=O) attached to an -O- group, indicating it is an ester, not an amide.
- **Compound II** features a carbonyl group (C=O) attached to a nitrogen (N), which is characteristic of an amide.
- **Compound III** contains a nitrogen attached to other substituents without a carbonyl, indicating it is an amine, not an amide.
- **Compound IV** has a nitrile group (C≡N) and does not fit the amide criteria.
- **Compound V** contains a carbonyl group (C=O) attached to an -OH group, identifying it as a carboxylic acid, not an amide.
Thus, **Compound II** is the only one that contains an amide functional group.
**Correct Answer:** Option II](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F3cb00ede-af09-4713-a061-065b07b08661%2F798f8817-3a15-408d-850b-3005b31e5136%2Fksv90im_processed.jpeg&w=3840&q=75)
